AARON F. DIOKEY, OF SOMERSET, PENNSYLVANIA,

CARTRlDGE SHELL.

SPECIFICATION forming part of Letters Patent No. 300,449, dated June 17,1884.

(No model.)

To all whom, it may concern:

Be it known that I, AARON F. DIUKEY, a citizen of the United States,residing at Somerset, in the county of Somerset and State ofPennsylvania, have invented a new and useful Paper Shell or Cartridge,of which the fo1- lowing is a specification, reference being had to theaccompanying drawings.

This invention relates to paper shells or cartridges; and it has for itsobject'to provide the same with a removable metallic breech.

A further object of my invention is to provide an improved form ofbreech, which, when screwed on the end of the shell or tube, serves tocrimp or turn in the edges of the shell, thereby making the attachmentmore secure.

A further object of my invention is to prevent the shell from spreadingwhen adjusting the breech or when discharging the gun.

"With these objects in view the said invention consists in certaindetails of construction and combination of parts, as hereinafter setforth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view ofmyimprovedshell or cartridge. Fig. 2 is a longitudinal sectional view ofthe same. Fig. 3 is a detail perspective view of the metallic breech.

Like letters of reference are used to designate corresponding parts inthe several ures.

Referring to the drawings, A designates the shell, constructed of paperor other suitable material.

B designates the metallic breech, comprising the cylindrical body 0,projecting forward and fitting within the shell, so as to serve as aprotection i'or the same when discharging the gun, the rear portion ofthe body being connected to a circular wall or cap, D. The rear portionof the body is provided with a circular series of teeth or crimpers, EE, preferably four in number, and a semicircular annular recess ordepression, F, is formed in the body, between the teeth and the circularcap D, said recess receiving the ends of the shell when the breech isadjusted on the same. An annular flange, G, extends outward from thecircular wall or cap D, and is milled on its edge, as shown, the fingersbeing applied to the milled edge of the circular cap, so as to turn thebreech in adjusting the same in position. A wall or flange, H, projectsfrom the circularcap D inwardly over the recess F, and is adapted toprevent the shell from spreading when the breech is being adjusted orwhen the gun is discharged. The circular cap or rear wall, D, is formedintegral with the body 0, and is provided in its center with a circularrecess, I, a small opening, J, being formed through said recess, for thepurpose well known in the art. The interior rear portion of the body isdished from the sides to the opening J; but I do not limit myself tothis construction.

The operation of my invention will be readily understood from theforegoing description,

taken in connection with the annexed draw-' ings. The metallic breech isapplied to the end of the shell by passing the projecting front end ofthe breech into the shell, the threads or teeth E engaging with the endsol the shell, so as to crimp the same and cause said ends to be receivedby the recess or depression F. It will be seen that the ends or edges ofthe shell will be crimped and turned in the semicircular annular recessF, while the wall or flange H will project over the recess and preventthe ends of the shell from being displaced, and will also serve toprevent the shell from spreading when the breech is being adjusted. Bythis means I am enabled to provide a safe and efficient attachment ofthe breech to the shell. The teeth or crimpers should be rounded ontheir lower edges to lessen the friction in adjusting the breech, andare arranged at equal distances apart. The metallic breech may be madeany desirable length, so as to project forward sufliciently to serve asa protection to the paper shell in discharging the gun, or as a guide tothe threaded part in ad justing it. The part of the breech entering theshell is made plain, so as to fit the inside of the same. I

My improved breech is simple and inexpensive in construction, and may bemanufactured at a slight cost.

Having described myinvention, I claim 1. In a shell or cartridge, theherein-described removable metallic breech, comprising the cylindricalbody, the circular cap at the rear end, the circular series of teeth orcrimpers, and the semicircular recess or depression at the rear thereof,for the purpose set forth.

2 The combination, with the shell or car-- comprising the cylindricalbody and circular cap formed integral, threads, teeth, or crimpers onthe exterior face of the body, a recess or depression between the teethand the circular cap, and a wall or flange projecting inward from thecap over the recess, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses. I

AARON F. DIGKEY.
